A pronunciation practice which I made to go with a Youtube video - 'English Language Club Consonant Pairs' 8mins (Thank you English Language Club!) I started with the video but you can do it any way round. Lots of sounds drilling! The words used are on the second page. You could get your students to write their own short sentences and practice with each other. You could use pictures or photos to pep it up, or have them cut up magazine pictures to make a storyboard to tell each other.
